"Watch out! I'm sending my messenger, and he will prepare the way before me. Then suddenly, the LORD you are looking for will come to his Temple. He is the messenger of the covenant whom you desire. Watch out! He is coming!" says the LORD of the Heavenly Armies.

"They'll be mine," says the LORD of the Heavenly Armies, "in the day when I prepare my treasured possession. I'll spare them, just as a man spares his own son who serves him.
